Fragrance compositions

FIELD OF THE INVENTION

The present invention relates to the field of perfumery. In particular, the present invention relates to fragrance compositions, as well as methods for making and using such fragrance compositions that can reduce and/or eliminate consumer fragrance habituation.

BACKGROUND OF THE INVENTION

It has been a long tradition that highly skilled perfumers carefully select fragrance oils to blend into a fragrance composition in order to provide a desired and long-lasting fragrance or scent with each application. In so doing, they need to bear in mind differences in the individual character, volatility, and/or odour detection threshold of the fragrance materials that are the components of the full fragrance. Conventional perfuming compositions have fragrance profile characterized by the presence of low volatile fragrance materials and volatile fragrance materials. The low volatile fragrance materials are known as “base notes”, while the volatile fragrance materials can be further divided into high volatile fragrance materials, identified as “top notes” or “head notes”, and medium volatile fragrance materials, identified as “middle notes” or “heart notes”.

The top notes tend to smell citrusy, green, light, fresh, and quickly evaporate due to their high volatility. Top notes are characterized by vapor pressure >0.1 Torr (Calculated using Advanced Chemistry Development (ACD/Labs) Software V11.02 ©1994-2013 ACD/Labs)). Middle notes are associated with floral aromas (e.g., jasmin, rose), fruity, marine or spicy aromas, and have an intermediate volatity in the vapor pressure range of 0.001 to 0.1 Tort Base or bottom notes are characterized as animalic, woody, sweet, amber or musky, not being very volatile, and having a vapor pressure <0.001 Torr.

In addition to the volatility, another important characteristic of a perfume raw material is its olfactory detection level. If a perfume raw material has a low odour detection threshold, otherwise known as “high odour impact”, only very low levels are required of the perfume raw material within a fragrance composition for it to be detected by the user, sometimes as low as a few parts per billion (i.e., ≦50 ppb). Conversely, if a perfume raw material has a high odour detection threshold (i.e., ≧50 ppb), otherwise known as a “low odour impact”, larger amounts of that material are required before it can be smelt by the user.

Conventional perfuming compositions can provide desirable scents initially, but over time consumers can become habituated to the perfume raw materials (PRMs) that form the fragrance. This means after a long period of time, the users and people around them can no longer detect the fragrance. Typically, the habituation problem can be found with perfume raw materials that are less volatile. That may be because the top notes are too volatile and linger around for so little time that the consumers do not have sufficient exposure to trigger the habituation effect. Whereas heart and base notes are on the skin and in the air around the consumer for long periods of time and therefore have ample time to induce habituation.

To overcome the habituation effect and allow consumers to continue to perceive the original scent, particularly over very long periods of time, consumers can: (1) use increasingly larger volumes of the fragrance composition; (2) continually re-apply the fragrance composition throughout the course of the day/evening, and/or (3) switch to a new fragrance composition containing different perfume oils for a significant period of time to reverse the habituation.

However, none of these solutions are particularly desirable. Option (1) can result in an an initial scent that is overpowering and possibly even offensive to the users and/or people around them. Option (2) tends to be costly and may not work since fragrance habituation of the perfume can lead to a diminished perception of the desired scent by the consumers, even when the quantity of the perfume material in the fragrance composition remains consistent and/or increases. The last solution is not particularly appealing either, especially, since many consumers have a signature perfume that they are known for and do not wish to switch.

Accordingly, there remains a need for an improved fragrance compositions that provide long-lasting and desirable scents that can reduce and/or eliminate the fragrance habituation effect in consumers, preferably over long periods of time. It is desirable that the solution to the habituation effect does not require consumers to modify their normal usage habits. It is further desirable to formulate a fragrance composition having improved longevity of the fragrance character, preferably components derived from the less volatile perfume raw materials (i.e., 0.1 to 0.001 Torr or ≦0.001 Torr) and/or having a low odour detection threshold (i.e., ≦50 ppb), preferably over long periods of time.

SUMMARY OF THE INVENTION

The Applicants have surprisingly discovered that perfume raw materials having certain chemical moieties are not subject to the fragrance habituation phenomenon. In a first aspect, the present invention is directed to a fragrance composition that includes a fragrance oil that comprises one or more perfume raw materials that resists fragrance habituation by a consumer to the composition. The perfume raw material is selected from the group consisting of: (a) from about 0.0000001% to about 10% of a perfume raw material comprising a thiol moiety; (b) from about 0.0000001% to about 10% of a perfume raw material comprising a sulfide moiety; (c) from about 0.000001% to about 10% of a perfume raw material comprising a thiazole moiety; (d) from about 0.0000001% to about 10% of a perfume raw material comprising an oxathiane moiety; (e) from about 0.000001% to about 10% of a perfume raw material comprising oxygen, sulfur, and nitrogen; (0 from about 0.00000005% to about 5% of a perfume raw material comprising a pyrazine moiety; (g) from about 0.00001% to about 20% of a perfume raw material comprising a nitrile moiety; (h) from about 0.000001% to about 10% of a perfume raw material comprising an indole moiety; (i) from about 0.00001% to about 10% of a perfume raw material comprising an oxime moiety; (j) from about 0.00001% to about 20% of a perfume raw material comprising an amine moiety; (k) from about 0.00000005% to about 5% of a perfume raw material comprising an isothiocyanate; (1) from about 0.00000005% to about 5% of a perfume raw material comprising a diamine moiety; and (m) mixtures thereof, with the proviso that the sum of the percentage of the perfume raw materials cannot exceed 100%.

In another aspect, the present invention relates to a method of resisting fragrance habituation of a fragrance composition by a consumer, the method comprising administering a fragrance composition as described herein above to the consumer.

One aim of the present invention is to provide a fragrance composition as described herein above which comprises perfume raw materials that can exhibit good fragrance anti-habituation properties, preferably over long periods of time at ambient conditions.

Another aim of the present invention is to provide such a fragrance composition as described herein above wherein the full fragrance “Odour Detection Threshold” remains substantively unchanged for the fragrance oils that contain perfume raw materials that resists the fragrance habituation of a consumer, preferably over long periods of time at ambient conditions.

A further aim of the present invention is to provide such a fragrance composition as described herein above wherein the perfume raw materials that resists the fragrance habituation of a consumer tend not to exhibit substantial decreases in the “Odour Detection Threshold” at ambient conditions after 2 hours, or after 4 hours, or after 6 hours, or after 8 hours, or after 10 hours, or after 12 hours, or intervals therein between or over long periods of time.

These and other features, aspects, and advantages of the present invention will become evident to those skilled in the art from the detailed description which follows.

DETAILED DESCRIPTION OF THE INVENTION

Definitions

As used herein, articles such as “a” and “an” when used in a claim, are understood to mean one or more of what is claimed or described.

As used herein, the terms “include”, “includes” and “including” are meant to be non-limiting.

As used herein, the term “ambient” refers to surrounding conditions at about one atmosphere of pressure, 50% relative humidity and about 25 C.°.

As used herein, the term “fragrance composition” includes a fine fragrance composition intended for application to a body surface, such as for example, skin or hair, i.e., to impart a pleasant odour thereto, or cover a malodour thereof. They are generally in the form of perfume concentrates, perfumes, eau de parfums, eau de toilettes, aftershaves, colognes, body splashes, or body sprays. The fine fragrance compositions may be ethanol based compositions.

As used herein, the term “consumer” means both the user of the fragrance composition and the observer nearby or around the user.

As used herein, the terms “fragrance material” and “perfume raw material” are used interchangeably and relate to a perfume raw material, or a mixture of perfume raw materials, that are used to impart an overall pleasant odour or fragrance profile to a composition. “Fragrance materials” can encompass any suitable perfume raw materials for fragrance uses, including materials such as, for example, alcohols, aldehydes, ketones, esters, ethers, acetates, nitriles, terpene hydrocarbons, nitrogenous or sulfurous heterocyclic compounds and essential oils. However, naturally occurring plant and animal oils and exudates comprising complex mixtures of various chemical components are also know for use as “fragrance materials”. The individual perfume raw materials which comprise a known natural oil can be found by reference to Journals commonly used by those skilled in the art such as “Perfume and Flavourist” or “Journal of Essential Oil Research”, or listed in reference texts such as the book by S. Arctander, <i>Perfume and Flavor Chemicals, </i>1969, Montclair, N.J., USA and more recently re-published by Allured Publishing Corporation Illinois (1994). Additionally, some perfume raw materials are supplied by the fragrance houses (Firmenich, International Flavors &amp; Fragrances, Givaudan, Symrise) as mixtures in the form of proprietary specialty accords. Non-limiting examples of the fragrance materials useful herein include pro-fragrances such as acetal pro-fragrances, ketal pro-fragrances, ester pro-fragrances, hydrolyzable inorganic-organic pro-fragrances, and mixtures thereof. The fragrance materials may be released from the pro-fragrances in a number of ways. For example, the fragrance may be released as a result of simple hydrolysis, or by a shift in an equilibrium reaction, or by a pH-change, or by enzymatic release.

As used herein, the term “fragrance profile” means the description of how the fragrance perceived by the human nose evolves over time from when it is first applied. It is a result of the combination of the top, middle and base notes, if present, of a fragrance. A fragrance profile is composed of 2 characteristics: ‘intensity’ and ‘character’. The ‘intensity’ relates to the perceived strength whilst ‘character’ refers to the odour impression or quality of the perfume, i.e., fruity, floral, woody, etc.

As used herein, the term “habituating” or “habituation” refers an individual or group who has decreased sensitivity to perceiving a fragrance or fragrance material. A fragrance or fragrance material is considered habituated when their Degree of Habituation (percent change in odor detection threshold or “ODT”) is greater than 150%, greater than 300%, greater than 500%, greater than 1000% according to the method described in the Test Methods section of this specification.

As used herein, the term “long periods of time” refers to both 1) a period of time after a single use of the fragrance composition, which may consist of multiple applications on a given use occasion, anywhere from 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 9 hours, 10 hours, 11 hours, 12 hours, 24 hours up to and beyond 36 hours, and 2) the days, weeks and months over which a consumer may use a fragrance on a regular basis. “Regular basis” is defined as more than a single occasion in a 4 week period and maybe daily, every other day, 2-3 times per week, at weekends only or on a weekly basis.

As used herein, the terms “modulator” and “fixative” are used interchangeably to designate an agent having the capacity to affect the fragrance profile by impacting the fragrance materials' evaporation rate. By incorporating the modulator, it is desired that the fragrance profile, preferably the volatile fragrance materials components, of the composition can be perceived by an observer or user thereof, over a longer period of time, as compared to the same perception in the absence of the modulator. In particular, according to the invention, alkoxylated methyl glucoside, preferably PPG-20 Methyl Glucose Ether (Glucam™ P-20 available from Lubrizol (USA)), is a modulator of the perceived tenacity of the compositions of the present invention, i.e., it is used to prolong the perceived intensity of the fragrance profile over time, as compared to the perception when PPG-20 Methyl Glucose Ether is not used in the composition. However, as discovered by the inventors, simply adding modulators to a traditionally constructed fragrance composition will not ensure an improved or enhanced fragrance profile over time. Instead, it is only when the modulators are added in the presence of reduce levels of low volatile fragrance materials can the intensity of the fragrance profile, preferably the volatile fragrance materials, be perceived for longer periods as compared to control composition absent the modulators and low levels of low volatile fragrance materials.

As used herein, the term “co-modulator” means an agent that is added to the composition in addition to the modulators and has the similar function of impacting the evaporation rate and intensity of the fragrance materials, so as to improve or prolong the perception of the fragrance profile by the consumer. Preferred example of a co-modulator is isocetyl alcohol (CERAPHYL® ICA; see PCT Publication No. WO2013/64412 (Firmenich)).

As used herein, the term “non-odorous” means an agent that does not impart an odour of its own when added into a composition of the present invention. For example, a “non-odorous modulator” such as PPG-20 Methyl Glucose Ether does not impart a new odour that alters the character of the composition to which it is added.

As used herein, the term “Odour Detection Threshold” refers to the lowest vapour concentration of that material which can be olfactorily detected. The ODT is measured according to the method disclosed in the Test Method Section herein below.

As used herein, the terms “perfume” and “fragrance” are used interchangeably to designate the component in the composition that is formed of fragrance materials, i.e., ingredients capable of imparting or modifying the odour of skin or hair or other substrate. As used herein, the term “vapor pressure” means the partial pressure in air at a defined temperature for a given chemical species. It defines a chemical species' desire to be in the gas phase rather than the liquid or solid state. The higher the vapour pressure the greater the proportion of the material that will, at equilibrium, be found in a closed headspace. It is also related to the rate of evaporation of a fragrance material which is defined in an open environment where material is leaving the system. The vapor pressure is determined according to the reference program Advanced Chemistry Development (ACD/Labs) Software Version 11.02, (©1994-2013).

It is understood that the test methods that are disclosed in the Test Methods Section of the present application must be used to determine the respective values of the parameters of Applicants' inventions as described and claimed herein.

In all embodiments of the present invention, all percentages are by weight of the total composition, as evident by the context, unless specifically stated otherwise. All ratios are weight ratios, unless specifically stated otherwise, and all measurements are made at 25° C., unless otherwise designated.

In yet another embodiment, the fragrance composition comprises one or more perfume raw materials comprising at least one sulfur, oxygen and nitrogen. Preferably, the perfume raw material is selected from the group consisting of 2-(4-methyl-1,3-thiazol-5-yl)ethanol; 1-(1,3-thiazol-2-yl)ethanone; 6-methyl-7-Oxa-1-thia-4-azaspiro[4.4]nonane; 2-[(furan-2-ylmethyl)sulfanyl]-5-methylpyrazine; 2,4-Dimethyl-5-acetylthiazole; 2-ethoxy-1,3-thiazole; 5-methoxy-2-methyl-1,3-thiazole; 1-(4,5-dihydro-1,3-thiazol-2-yl)ethanone; 1-(1,3-thiazol-2-yl)propan-1-one; 1-(2,4-dimethyl-1,3-thiazol-5-yl)ethanone; 2-amino-4-methylsulfanylbutanoic acid; (2S)-2-amino-4-methylsulfanylbutanoic acid; 8-Hydroxy-5-quinolinesulfonic acid; 2-aminoethanesulfonic acid; 2-phenyl-3H-benzimidazole-5-sulfonic acid; and mixtures thereof.

While not wishing to be bound by theory, Applicants believe that habituation is a phenomenon that is grounded in the consumer's physiology, in that the body is attempting to avoid having its sense of smell from being overwhelmed by any one stimulus after repeated chronic exposure to the stimulus. As such, habituation is likely a darwanian mechanism that has evolved over time. However, certain odours associated with danger and/or conditions that may be detrimental to or important in sustaining life are not subject to the habituation phenomenon. As a result, Applicants looked to odours that may be associated with danger and/or life essential conditions as Applicants believed that the evolutionary path of those who became habituated to such odours would have been cut short.

Surprisingly, Applicants have identified certain chemical moities that are associated with conditions that may be detrimental to or important in sustaining life. Based on this recognition, Applicants identified chemical moieties that are therefore not susceptible to fragrance habituation, and corresponding perfume raw materials comprising such chemical moieties. Accordingly, Applicants believe that fragrance compositions can resist fragrance habituation by incorporating perfume raw materials having these chemical moieties. Additionally, Applicants developed processes for making and using such fragrance compositions that are not susceptible to fragrance habituation.

Many consumers prefer fragrance compositions that can consistently provide a desired scent, or fragrance, that can be perceived upon application of the product and preferably for a long period of time thereafter. Habituation of the perfume raw materials by the consumer, however, can lead to a diminished perception of the desired scent, even when the quantity of perfume raw materials in the fragrance composition remains consistent and/or increases.

In yet another embodiment, a fragrance composition of the present invention can exhibit a fragrance anti-habituating effect on a consumer as having, for example: <ul id="ul0009" list-style="none"><li id="ul0009-0001" num="0000"><ul id="ul0010" list-style="none"><li id="ul0010-0001" num="0077">a) a two week anti-habituation index of at least 0, 1, 2, 3 or 4;</li><li id="ul0010-0002" num="0078">b) a four week anti-habituation index of at least 0, 1, 2, 3, or 4;</li><li id="ul0010-0003" num="0079">c) a two week anti-habituation index of 0, 1, 2, 3 or 4; and/or</li><li id="ul0010-0004" num="0080">d) a four week anti-habituation index of 0, 1, 2, 3 or 4</li></ul></li></ul>

In another aspect, fragrance oils may comprise many different types of perfume raw materials. Each perfume raw material differs from another by several important properties including individual character, volatility, and olfactory detection level. By bearing in mind these different properties, and others, the perfume raw materials can be blended to develop a fragrance composition with an overall desirable and long-lasting specific character profile.

For example, the less volatile and more substantive perfume raw materials are typically used to give animalic, woody, sweet, amber or musky characters. They may be detected soon after application and also last longer than more volatile PRMs. However, due to the habituation effect as noted above, the users cease to notice their scents after a period of time (e.g., after 2 hrs from application), especially over long period of time.

Accordingly, the Applicants believe that certain less volatile perfume raw materials can be incorporated into a fragrance composition to resist the habituating effect. Therefore, in another embodiment, the perfume raw materials disclosed herein present in the fragrance composition are selected from: (i) perfume raw materials having a chemical moiety selected from the group consisting of: a thiol moiety, a sulfide moiety, a thiazole moiety, an ozathiane moiety, a pyrazine moiety, an indole moiety, an oxime moiety, an amine moiety, an isothiocyanate moiety, a diamine moiety, compounds comprising oxygen, sulfur and nitrogen, and mixtures thereof; and (ii) wherein the perfume raw materials have a vapor pressure of less than 0.1 Torr, or 0.1 to 0.001 Torr, or less than 0.001 Torr.

In addition to volatility, olfactory detection level, otherwise known as the odour detection threshold of perfume raw materials is an important property that can influence fragrance habituation. For example, if a perfume raw material has a low odour detection threshold, otherwise known as “high odour impact”, then very low levels of the perfume raw materials (i.e., ≦50 ppb) can be easily detectable by the consumers. However, due to the habituation effect as noted above, the users cease to notice their scents after a short period (e.g., after 2 hrs from application).

Accordingly, the Applicants believe that certain low odour detection threshold perfume raw materials can be incorporated into a fragrance composition to resist the habituating effect. Therefore, in another embodiment, the perfume raw materials disclosed herein present in the fragrance composition are selected from: (i) perfume raw materials having a chemical moiety selected from the group consisting of: a thiol moiety, a sulfide moiety, a thiazole moiety, an ozathiane moiety, a pyrazine moiety, an indole moiety, an oxime moiety, an amine moiety, an isothiocyanate moiety, a diamine moiety, compounds comprising oxygen, sulfur and nitrogen, and mixtures thereof; and (ii) wherein the perfume raw materials have an odour detection threshold of less than 50 parts per billion (ppb).

Fragrance Modulators

In one aspect, the perfume composition may contain a fragrance modulator. Fragrance modulators enhance intensity of a fragrance profile over time, preferably so that the volatile fragrance materials remain significantly consistent from its initial impression to the end. Fragrance modulators are disclosed in U.S. Provisional Patent Ser. No. 61/915,514 (P&amp;G) which is incorporated by reference.

Test Methods

The following assays set forth must be used in order that the invention described and claimed herein may be more fully understood.

Test Method 1: Determining Vapor Pressure

In order to determine the vapor pressure for the fragrance materials, go to the website haps://scifinder.cas.org/scifinder/view/scifinder/scifinderExplorejsf and follow these steps to acquire the vapor pressure.

1. Input the CAS registry number for the particular fragrance material.

2. Select the vapor pressure from the search results.

3. Record the vapor pressure (given in Torr at 25° C.).

SciFinder uses Advanced Chemistry Development (ACD/Labs) Software Version 11.02. (© 1994-2013). If the CAS number for the particular fragrance material is unknown or does not exist, you can utilize the ACD/Labs reference program to directly determine the vapor pressure.

Test Method 2: Degree of Habituation

The Degree of Habituation to a fragrance composition containing a perfume raw material can be determined by exposing a human panel to daily exposures of the perfume over a four week period. The Degree of Habituation can be calculated at both the week two and week four time points, relative to the initial baseline time point.

For each exposure panel test, more than 15 panelists are recruited, and then exposed to the test scent in a manner, frequency, and concentration indicated by the intended product end use, but including at least one exposure per day every day for four consecutive weeks. The perfume exposure must be sufficient that the panelists can detect the perfume of interest being delivered from the product or perfume delivery system contained within the product. The criteria for recruitment onto the exposure panel requires that panelists be typical consumers of the product in question, who agree to use the scent being tested, are non-smokers, and free of nasal congestion and allergies. The degree of habituation is calculated and reported as the percent change in the Odor Detection Threshold (ODT) value at week 2 and at week 4, versus the initial baseline ODT value. Since the degree of habituation is a relative measure, it accommodates the variation in absolute ODT values which can arise between different testing laboratories.

Raw materials and finished products comprising them can be used in conjunction in order to determine the degree of habituation. For example, daily exposures to the panelists may involve the use of a finished product while the ODT test measurements may involve the use of the respective neat perfume or PRMs. The conditions selected for use in either the daily exposures or in the ODT testing must be applied uniformly across all panelists, and remain unchanged for the entirety of the testing period. When the test perfume materials are available in their simple forms i.e., PRMs, neat perfumes, or fine fragrances, unincorporated into complex products or delivery systems, then the ODT test is to be conducted with these simple forms via an olfactometer, as this is the preferred method.

When these simple forms of the test perfume materials are inaccessible for testing, then the ODT test may be conducted with finished products or complex formulations comprising the test perfume materials. Presentation devices other than an olfactometer may be required when conducting the ODT testing on finished products or complex formulations, and may include devices such as sniff cups, headspace chambers and capped bottles, as allowed for in the test method ASTM E679-04 described below.

The ODT value for each panelist is determined at each of three time points the during four week daily exposure period, namely; at an initial baseline, at two weeks, and at four weeks. The ODT values are always determined in accordance with test method ASTM E679-04 (Standard Practice for Determination of Odor and Taste Thresholds by a Forced-Choice Ascending Concentration Series of Limits) as reapproved in 2011 except, the following replaces the protocol of such test method's Sub-articles 4.4, 8.2 and 8.3.

Sub-article 4.4, Individual best-estimate values of the threshold are derived from the pattern of correct/incorrect responses produced separately by each panelist. The group average ODT value at a given time point is derived by fitting the entire data set from all panelists at that time point to a Log Logistic Regression Model.

Sub-article 8.2, If the concentration range has been correctly selected, it is not necessary that all panelists judge correctly within the range of concentration steps provided. Thus, the representation of the panelists' judgments as in 8.1 need not terminate with two or more consecutive plusses (+).

Sub-article 8.3, Since there is a finite probability that a correct answer will occur by chance alone, it is important that a panelist repeat the test three times. Panelists who fail the test at the highest concentration, are deemed anomic to the test material and their response is removed from the data set.

Additionally, the following selections are made in accordance with the test method's sub-articles 1.3, 1.4, 1.6, 1.7, and 4.1, and specified here as per sub-article 9.3.

Sub-article 1.3, The threshold is characterized as being a) only detection (awareness) that a very small amount of added substance is present but not necessarily recognizable.

Sub-article 1.4, When the preferred method is being conducted, namely using a simple perfume form presented via olfactometer, then the presentation medium is an air and pure nitrogen mix. When testing finished or complex products, alternative presentation media may be used, such as air.

Sub-article 1.6, When the preferred method is being conducted, namely using a simple perfume form presented via olfactometer, then the physical method of presentation is at a rate of 40 L/min. When testing finished or complex products, alternative presentation devices may be used, including but not limited to sniff cups, headspace chambers or capped bottles.

Sub-article 1.7, Presentation is made to a panel of greater than 15 panelists, who are participating in the daily exposure panel.

Sub-article 4.1, Eight scale steps are used, with each step having an individual predetermined dilution factor suitable for the stimuli being tested, at a temperature of 35° C. PRM or neat perfume stimuli are typically introduced to the olfactometer system in the neat form via a pump syringe. Sometimes a dilution of the stimuli with ethanol is needed.

The group average ODT values from the three time points are used to calculate the degree of habituation. The degree of habituation is reported for 2 specific time points, as the percent change in group average ODT at one time point, relative to the group average ODT at the initial baseline time point. The degree of habituation is determined at the time points of: 2 weeks and 4 weeks, of the four week daily exposure period, using the following formula: <br />Degree of Habituation(percent change in ODT) at Time <i>X</i>=((Group Average ODT_{(Time X)}−Group Average ODT_(Baseline)/Group Average ODT_(Baseline))×100<br /> where Time X is either 2 weeks, or 4 weeks, of repeated daily exposure. <br /> Anti-habituation Index:

A perfume is considered to have an anti-habituation index of:

All documents cited in the Detailed Description are, in relevant part, incorporated herein by reference; the citation of any document is not to be construed as an admission that it is prior art with respect to the present invention. To the extent that any meaning or definition of a term in this document conflicts with any meaning or definition of the same term in a document incorporated by reference, the meaning or definition assigned to that term in this document shall govern. The perfume raw materials disclosed, claimed and/or used in the perfumes claimed and/or described herein encompass any stereoisomers of such perfume raw materials.

Unless otherwise noted, all component or composition levels are in reference to the active portion of that component or composition, and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources of such components or compositions.

All percentages and ratios are calculated by weight unless otherwise indicated. All percentages and ratios are calculated based on the total composition unless otherwise indicated.

It should be understood that every maximum numerical limitation given throughout this specification includes every lower numerical limitation, as if such lower numerical limitations were expressly written herein. Every minimum numerical limitation given throughout this specification will include every higher numerical limitation, as if such higher numerical limitations were expressly written herein. Every numerical range given throughout this specification will include every narrower numerical range that falls within such broader numerical range, as if such narrower numerical ranges were all expressly written herein.

The dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as “40 mm” is intended to mean “about 40 mm.”

Every document cited herein, including any cross referenced or related patent or application and any patent application or patent to which this application claims priority or benefit thereof, is hereby incorporated herein by reference in its entirety unless expressly excluded or otherwise limited. The citation of any document is not an admission that it is prior art with respect to any invention disclosed or claimed herein or that it alone, or in any combination with any other reference or references, teaches, suggests or discloses any such invention. Further, to the extent that any meaning or definition of a term in this document conflicts with any meaning or definition of the same term in a document incorporated by reference, the meaning or definition assigned to that term in this document shall govern.

While particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
